The NEG glass block is currently available in various patterns, sizes and colours to meet any architectural requirement. The patterns permit light control direct transmission, diffusion, and reduction. Moreover, transparent and non- transparent patterns may be used according to the purpose of the glass block wall. The non-transparent glass block is suitable for securing a private space while the transparent glass block is effective for producing the openness. The Light Directive Glass Block directs light upwards to brighten the ceiling and the Solar Reflective Glass Block sharply reduces solar heat. Corner block permits one continuous glass block wall surface. A circular block is also available. Prism Glass is available for use in pavements, bridges and "top lights." The Rhythmicolor Glass Block accentuates the appearance. The NEG glass block designs (patterns, sizes, colours) are thus amenable to the planning objective.

N.E.G. Glass Blocks are equally suitable for both commercial and domestic applications. The natural lighting requirements for any room can be satisfied from the N.E.G. range.
